Answer:
y=-4/7
Step-by-step explanation:
7y/2=-2
multiply both sides by 2
7y=-4
divide both sides by 7
y=-4/7
When using substitution, we are imputing an equation in place of a variable to eliminate one of the variables in the equation so that we can solve for the remaining variable.
For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.
3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)
Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
x=11

Answer:
As 
approaches infinity 
approaches negative infinity.
Step-by-step explanation:
As you can see in the graph as grows larger in the negative direction, the 
increases in the negative direction too.
Thus:
Answer:
The factorised term is:
Step-by-step explanation:
We are asked to factor the algebraic expression given as:
Now we will take out the variable which is common among all the terms and write the remaining expression in parantheses.
As 
is common among all the terms hence we write this term out of the parantheses and the remaining term inside it as to obtain then simplified expression as:
30; If you add and subtract these numbers you should get 30%
